Used to be the Pearstone ShutterBoss, which is the one I got, but this one should be identical.

Edit: Actually, I wanted to control a Rebel as well, so I got the Rebel version (sub-mini jack) and sacrificed a cheap N3 remote and made a sub-mini-to-N3 adapter. They might sell such an adapter nowadays, though.

Just type 'tc-80n3' into ebay, you'll get a few hundred results.Apparently the Link Delight ones aren't so bad for $20, google that and you'll get a lot of happy people. One major difference though is that the Link Delight ones don't have a locking plug, so it may fall out occasionally.Still, cheaper than the genuine version (that said, I got my genuine tc-80n3 off ebay, 2nd hand for about $50).

only pain in the ass is there is no on / off switch so you just have to take the batteries out when finished not a big deal really

To be fair, you can't turn off the genuine Canon TC-80N3 either.I keep my battery in there, but reversed, it's perfectly usable as a remote switch without power. If I want timer functions, then I just take the battery out, reverse it, and use it as intended.

for some rebels there was/is a hacked firmware with a solid intervalometer included

I had a Canon Wired Remote from my Rebel/Elan 7 days and converted it to use on the 5D2. I bought the following adapter with an "N3" plug on the end (see link below). Then I picked up a 2.5mm (F) to 3.5mm (M) stereo converter from Radio Shack for buck or two. I connected one into the other and it worked without a problem!

Heh, I don't know if you can have reliable and cheap at the same time, but as others have stated eBay has tons of them and for the 30 bucks they are asking, that's probably as reliable and cheap as you're going to get.

I didnt know that, never used the genuine one

The absence of an off switch is mentioned as a downside quite often and I don't really understand why. The power consumption is minuscule, probably equivalent to a digital watch, yet nobody fears leaving the battery in a digital watch.
